Nora chanced a quick nod when the Doctor began moving and indicated for her to stay quiet. She could feel her heart pounding and she was finding it difficult to breath. Her gaze slid from the woman to the back of the two men's heads. They were talking to eachother, so far not noticing the fact that there were actually two conscious women in their backseat. 

She looked back at the Doctor, moving her head ever so slightly. She saw the device from before in on of the other women's hands and a key in the other. Nora was watching with warped fascination as the Doctor put the two objects together and a noise filled the air. She glanced over towards the front seat in time to see their heads turning and Nora began to act natural. At least as naturally as one could act in this situation. She avoided looking at the two, and gazed down at her sister, stroking Evie's long blonde hair as a reassuring gesture. Evie's lips parted and she let out a soft moan, but beyond that and her breathing she showed no signs of life. Nora doubted she would wake up anytime soon, and even when she did she would be delirious. 

"What do you want with us?" Nora heard herself ask, her voice surprisingly steady. She was talking to the kidnappers, obviously, but she was refusing to look either of them in the eye.
